The Reznor EnviroPak is a new generation of gas fired air heater providing combined heating and ventilation with optional cooling. The units are available as either indoor or outdoor models with a wide range of heat outputs and cooling capacities.
The pre-insulated module contains a cross flow heat exchanger with an incorporated bypass and a return air fan.
Different levels of filtration are available, G4 to F7. These will filter both the fresh and the return air introduced to the module.
